Carriage speed control of a cross-lapper system for nonwoven web quality

In a cross-lapper system, the carriage unit is used to make uniform web in appropriate width and thickness. Traditionally, this is a stable, sluggish system with large attenuation of the input in the steady state. In this paper, the modeling, stability, order reduction, dynamic analysis and controll...

Description
Summary:In a cross-lapper system, the carriage unit is used to make uniform web in appropriate width and thickness. Traditionally, this is a stable, sluggish system with large attenuation of the input in the steady state. In this paper, the modeling, stability, order reduction, dynamic analysis and controller design of a cross-lapper system for good nonwoven web quality will be presented to deal with this issue. A realizable controller is designed which can not only make the closed-loop system efficient for good tracking property but also can achieve the meaningful design objectives. The performance can be effectively shown from the computer simulation.
